Abstract

The disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communication. The UE first receives first information, the first information indicating a first list and a second list, and then the UE monitors paging information in at least one of a first serving cell and a second serving cell; an area identifier corresponding to the first serving cell belongs to the first list, and an area identifier corresponding to the second serving cell belongs to the second list; and the first list and the second list can be updated separately. Through the designs of the first list and the second list and updating the first list and the second list separately, the disclosure improves the efficiency of mobility management at network side and the maintenance of tracking areas and reduces the complexity of paging design, and thus improves the overall performance.

First claim

What is claimed is:

1. A method in a User Equipment (UE) for wireless communication, comprising:
receiving first information, the first information indicating a first list and a second list; and
monitoring paging information in at least one of a first serving cell and a second serving cell;
wherein an area identifier corresponding to the first serving cell belongs to the first list, and an area identifier corresponding to the second serving cell belongs to the second list; the first list and the second list comprise Q 1 area identifier(s) and Q 2 area identifier(s) respectively, the Q 1 and the Q 2 are positive integers respectively; and the first list and the second list can be updated separately.

2. The method according to claim 1 , comprising:
receiving second information, the second information indicating a first area identifier; and
judging at least one of whether the first area identifier belongs to the first list or whether the first area identifier belongs to the second list;
wherein when the first area identifier is outside the first list, the receiving of the second information triggers a transmitting of third information; when the first area identifier is outside the second list, the receiving of the first information triggers a transmitting of fourth information.

3. The method according to claim 2 , comprising:
transmitting target information; and
receiving feedback information;
wherein the target information is the third information, or the target information is the fourth information; the transmitting of the target information is used for triggering the receiving of the feedback information.

4. The method according to claim 1 , comprising:
receiving fifth information;
wherein the UE judges only one of whether the first area identifier belongs to the first list or whether the first area identifier belongs to the second list; and the fifth information is used for determining a judgment on whether the first area identifier belongs to the first list or a judgment on whether the first area identifier belongs to the second list.

5. The method according to claim 1 , comprising:
determining a first time-frequency resource set and a second time-frequency resource set;
wherein the UE monitors paging information in the first time-frequency resource set of the first serving cell and the second time-frequency resource set of the second serving cell respectively, location information of the UE is used for determining the first time-frequency resource set, and the second time-frequency resource set is unrelated to the location information of the UE;
or, wherein the area identifier corresponding to the first serving cell is equal to the area identifier corresponding to the second serving cell.

6. A method in a first network equipment for wireless communication, comprising:
transmitting first information, the first information indicating a first list and a second list; and
transmitting paging information in a first serving cell;
wherein an area identifier corresponding to the first serving cell belongs to the first list, and an area identifier corresponding to a second serving cell belongs to the second list; the first list and the second list comprise Q 1 area identifier(s) and Q 2 area identifier(s) respectively, the Q 1 and the Q 2 are positive integers respectively; the first list and the second list can be updated separately; a receiver of the first information comprises a first terminal; the first network equipment is related to the first serving cell.

7. The method according to claim 6 , comprising:
receiving target information; and
transmitting feedback information;
wherein the target information is third information, or the target information is fourth information; the receiving of the target information is used for triggering the transmitting of the feedback information; when the first area identifier is outside the first list, the target information is the third information; when the first area identifier is outside the second list, the target information is the fourth information; the first list and the second list comprise Q 1 area identifier(s) and Q 2 area identifier(s) respectively, the Q 1 and the Q 2 are positive integers respectively; and the first list and the second list can be updated separately.

8. The method according to claim 6 , comprising:
configuring a first time-frequency resource set;
wherein the first terminal monitors paging information in the first time-frequency resource set of the first serving cell, and location information of the first terminal is used for determining the first time-frequency resource set;
or, wherein the area identifier corresponding to the first serving cell is equal to the area identifier corresponding to the second serving cell.

9. A UE for wireless communication, comprising:
a first receiver, to receive first information, the first information indicating a first list and a second list; and
a second receiver, to monitor paging information in at least one of a first serving cell and a second serving cell;
wherein an area identifier corresponding to the first serving cell belongs to the first list, and an area identifier corresponding to the second serving cell belongs to the second list; the first list and the second list comprise Q 1 area identifier(s) and Q 2 area identifier(s) respectively, the Q 1 and the Q 2 are positive integers respectively; and the first list and the second list can be updated separately.

10. The UE according to claim 9 , comprising:
a first transceiver, to receive second information, the second information indicating a first area identifier, and to judge at least one of whether the first area identifier belongs to the first list or whether the first area identifier belongs to the second list;
wherein when the first area identifier is outside the first list, the receiving of the second information triggers a transmitting of third information; when the first area identifier is outside the second list, the receiving of the first information triggers a transmitting of fourth information.

11. The UE according to claim 10 , wherein the first transceiver transmits target information, and the first transceiver receives feedback information; the target information is the third information, or the target information is the fourth information; the transmitting of the target information is used for triggering the receiving of the feedback information.

12. The UE according to claim 10 , wherein the first transceiver receives fifth information; the UE judges only one of whether the first area identifier belongs to the first list or whether the first area identifier belongs to the second list; and the fifth information is used for determining a judgment on whether the first area identifier belongs to the first list or a judgment on whether the first area identifier belongs to the second list.

13. The UE according to claim 9 , wherein the second receiver determines a first time-frequency resource set and a second time-frequency resource set; the UE monitors paging information in the first time-frequency resource set of the first serving cell and the second time-frequency resource set of the second serving cell respectively, location information of the UE is used for determining the first time-frequency resource set, and the second time-frequency resource set is unrelated to the location information of the UE;
or, wherein the area identifier corresponding to the first serving cell is equal to the area identifier corresponding to the second serving cell.
